I don't know of any feature like that, but maybe you can do the
following in your script/files:

\set lastquery 'your-query-here'

so that you can do something like

explain :lastquery;

But if you are able to manipulate your scripts you can just insert the
explain by hand on queries you are interested in, or use autoexplain
for all the queries.
